A particle starting from rest, moves with a uniform acceleration and covers $x$ meters in the first $5\, second$. The same particle will cover the following distance in the next $5\, seconds$ :-
A particle travels $10\,m$ in first $5\, sec$ and $10\,m$ in next $3 \,sec$. Assuming constant acceleration what is the distance travelled in next $2 \,sec$..........$m$
A small electric car has a maximum constant acceleration of $1\,m / s ^2$, a maximum constant deceleration of $2\,m / s ^2$ and a maximum speed of $20\,m / s$. The amount of time it would take to drive this car $1\,km$ starting from rest and finishing at rest is $.........\,s$
